Question: How is it possible that at the end of the film, when the helicopters are arriving to New York, many people are coming out of the buildings. Aren't they supposed to be frozen?

Question: Most tsunami are caused by earthquakes underwater that trigger a huge wave. However, there are no earthquake-causing fault lines anywhere near New York City. So what caused the tsunami?

Answer: That's not a tsunami - it's a catastrophic rise in sea level caused by the disruption in the ocean's balance. Same basic effect, different cause.

I say it's a storm surge.

Question: At the beginning of the film, Jack Hall quickly explains how global warming could cause an ice age by altering the global ocean currents. The explanation is short and I didn't catch all of it. Could someone explain in more detail, preferably as simply as possible?

Chosen answer: Global warming melts the icecaps, releasing millions of tons of fresh water into the oceans. This upsets the delicate environmental balance of the oceans, leading to the ocean currents stopping. It's these currents that carry warm water up into the Northern Hemisphere, causing our temperate climate. The currents stop, everything cools down, fast.
